“This study focuses on the problem of orderly seed flow damage caused by seed collision and stacking during high-speed sowing, and introduces its research progress in the field of precision sowing of corn. The research team established a dynamic model of corn seed transport and explored the optimal parameter combination of the annular gap injection structure, providing a solution to the quality deterioration problem of gravity based seeding and a theoretical basis and engineering reference for optimizing the seeding scheme of the air suction precision seeding system.”
